Seeing Safely: Running mixed criticality applications on a single embedded platform

Avionics display systems provide two types of data to a pilot: high-reliability information that is integral to the safe operation of the aircraft, and non-critical information. This presentation will explore how a single embedded computer can be configured to reliably carry out both functions in parallel. Topics of discussion will include:

• Partitioning the CPU and GPU to run on more than one operating system, such as a safety-critical RTOS and application software certified to safety critical standards and a non-safety critical partition for other applications or operating systems.
• Running safety critical and non-safety critical information on different displays
• Impacts of a dual-purpose architecture on safety-certification
